What lighting device uses a metal disc with slots that can be rotated to produce movement in the light?

• A. Animation Disc
• B. Hot Spot
• C. IATSE
• D. Freie Buhne

Answer: (A)

An animation disc is a metal disk with cutouts or slots around its edge. When mounted in front of a light and rotated, the slots pass in and out of the beam, creating moving patterns on stage. This mechanical rotation produces light movement and texture without changing the light itself. The other terms don’t describe a device with rotating slots: a hot spot is just the bright center of a beam, IATSE is a theatre union, and Freie Bühne refers to a type of theatre, not a lighting accessory.
